The Call Stack window lists the sequence of calls made during execution. When the debugger is suspended, the Call Stack window shows the sequence of function calls (i.e., the call stack). On initial suspension, the top-most stack frame is selected automatically.
Double-click on a function call in the window to go to that line in the editor. If the call is made to a PHP class, the Navigator window will also go to that line when you double-click the call.
You can double-click on a call stack frame to select it, then explore any variable or expression values for that frame in the Variables and Watches windows.
The following table describes the icons displayed to the left of the call name.
| Icon | Description |
|---|---|
|
The current call on the call stack |

A call other than the current call |
